将数据从Tkinter插入到Sqlite3 - sqlite3.OperationalError：near“）”：语法错误

-1

很多人发布了关于此错误的消息，但是我无法弄清楚。将数据从Tkinter插入到Sqlite3 - sqlite3.OperationalError：near“）”：语法错误

这是我的Tkinter GUI的一个画面：

当用户点击保存，我想“广告系列”条目是数据库的名称，然后我想“工人”的条目被添加到名为（工人）的表中。

我认为问题是当我尝试将信息添加到for loop和c.execute("insert into workersNames (workers)", element)表中时，但这可能只是其中一个问题。

你的'insert'语句没有说什么要插入。请参阅[插入语句文档]（https://sqlite.org/lang_insert.html）。 – user2357112

@ user2357112我添加了'values'看起来像这样'\t \t \t c.execute（“insert into workersNames values（workers）”，element）'但现在错误是sqlite3.OperationalError：no such column：workers'但我认为该列是在创建表的行中创建的？我使用[link]（https://stackoverflow.com/questions/16120474/save-button-with-python-tkinter-sqlite）作为我的代码的模型。 – nasan

要插入人员纳入数据库，请使用：

c.execute("insert into workersNames (workers) values (?)", (element,))

我意识到你有很多的未连接到任何Tkinter的部件self.xx = tk.StringVar()秒。因此，当您拨打sef.xx.get()时，您会收到一个空字符串。我删除了tk.StringVar()以使代码缩短以供测试，并在tkinter条目上使用get()方法来获取其内容。

因此：

names = [self.workersStr1.get(), self.workersStr2.get(), self.workersStr3.get()]

变成了：

names = [self.workersEntry1.get(), self.workersEntry2.get(), self.workersEntry3.get()]

通知我改变了所有的条目到类使用self关键字属性。

下面是完整的代码，你可以通过和看到的变化：

#import tkinter as tk 
#from tkinter import * 
#from tkinter.ttk import * 
#import sqlite3 

import Tkinter as tk

     self.pack(fill=BOTH, expand=True) 

     # CAMPAIGN 
     campFrame = Frame(self) 
     campFrame.pack(fill=X) 

     campLbl = Label(campFrame, text="Campaign: ", width=8) 
     campLbl.pack(side=LEFT, padx=5, pady=5)

     self.workersEntry3 = Entry(workersFrame) 
     self.workersEntry3.pack(fill=X, padx=5, expand=True) 


     # SAVE 
     saveFrame = Frame(self, relief=RAISED, borderwidth=1) 
     saveFrame.pack(fill=BOTH, expand=True) 

     saveButton = Button(self, text="Save", command = self.SaveDetails) 
     saveButton.pack(side=RIGHT, padx=5, pady=5) 


    def SaveDetails(self): 
     # Create Database 
     conn = sqlite3.connect(self.campEntry.get() + ".db") 
     c = conn.cursor() 

     # Create Table - workersNames

      workers text)''') 
     conn.commit() 

     # Add data to table 
     names = [self.workersEntry1.get(), self.workersEntry2.get(), self.workersEntry3.get()] 

     for element in names: 
      c.execute("insert into workersNames (workers) values (?)", (element,)) 
     conn.commit() 

     c.close() 
     conn.close() 



def main(): 
    root = Tk() 
    root.geometry("300x300+300+300") 
    app = Research(root) 
    root.mainloop() 

if __name__ == '__main__': 
    main()

这将产生以下结果：

希望它有助于。
